Based on the grey theory DGM (1,1) model, the ship magnetic field at different depths is predicted. COMSOL is used to simulate the ship’s magnetic field, and the simulated magnetic field value is applied to the established model. The gray model is used to predict the ship’s underwater magnetic field at different depths, which verifies the effectiveness of the gray prediction model.
